12 as much money left as Sabrina. How much money did the two girls have at first?

Sabrina |
Lynn |
| Before |
17 u + 88 |
21 u + 44 |
| Change |
- 17 u |
- 21 u |
| After |
$88 |
$44 |
Amount that Lynn had left
=
12 x 88
= $44
The amount that Sabrina and Lynn had at first is the same.
21 u + 44 = 17 u + 88
21 u - 17 u = 88 - 44
4 u = 44
1 u = 44 ÷ 4 = 11
Amount that Sabrina had at first
= 17 u + 88
= 17 x 11 + 88
= 187 + 88
= $275
Total amount that both girls had at first
= 2 x 275
= $550
Answer(s): $550
